What is the thing that you put in your wii and lets you get hundreds of Wii games I know its a hard drive but what kind

i dont think there is one but there's a disc that gives you wii points so you can download from wii ware

- In fact, there is. Any standard USB Hard Drive will do (MOST work flawlessly, it's best to check GBATemp.net's compatibility table or ask there). Personally I'm using a Chieftec HDD Enclosure and a standard 3,5 250Gb hard drive inside of it. The Wii has to be softmodded though, instructions on how to softmod it can be found on GBATemp.net aswell.
